When running from live usb system It is no longer faster to boot directly from flash drive than from RAM and copy LL to ram unless md5sum skipping
https://askubuntu.com/questions/829917/c...e-the-disk
Lets say that:
my usb takes 60 seconds to read about 1,5gb (LL install media)
my RAM takes 1 second to read about 1,5gb (LL install media)
my computer boot into the LL loading stage in about 10seconds
my usb takes about 15seconds to read about 350mb (LL essential files to boot up)
Then:
booting normally with LL 4.8 takes about 25seconds (with toram disabled and md5sum disabled)
booting with toram with LL 4.8 takes about 70seconds (with toram enabled and md5sum disabled)
booting normally with LL 5.x takes about 70seconds (with toram enabled and md5sum disabled)
booting with toram with LL 5.x takes about 71seconds (with both toram and md5sum enabled) md5sum checking can be done in ram
However using toram boot parameter with less RAM than needed result in crash while booting (out of RAM)
